Systems or processes containing multiple fluids can often benefit from dye tracers added to permit quick visual identification. Dyes can also help in rapid identification of leaks and to avoid confusion in use of stock fluids. Nova offers products to suit a full range of fluids and applications. All dyes are non-reactive, heat and chemically stable making them ideal long-lived tracers.

For oil based or hydrocarbon fluids: Novasolve or Novalube dyes are available in a full range of colors. Typical use rate is 5-20 ppm. Darker fluids require higher dosing rates.

For invisible marking of fluids use Novaflour dyes. When added at 10-20 ppm the dye will not visibly color the fluid but will glow a bright yellow or green under UV light.
